In 1930, the FBI
assumed responsibility for managing the Uniform Crime Reporting (UCR)
program, collecting
data from 400 cities. By 2006, over 15,000 law enforcement
agencies submitted crime reports to the FBI, but since not all
jurisdictions provide reports there is a
possibility that you won't find complete data on some of our agency
crime report pages. In every case where the FBI has assigned
a
population to a jurisdiction, we are providing a page even though it
may
be blank. When a city located in a county starts
submitting its
own reports, the population assigned to the county is reduced to
reflect that fact.

The UCR can be presented here because of the hard work of law
enforcement
statisticians who must classify and score each crime according to
the strict criteria developed for the UCR. Some
agency's crime reports do not have a
population associated with them, these may include: the highway patrol,
state
police, a drug enforcement agency, an environmental enforcement agency,
a transportation utility, colleges, and others. Areas may
have many agencies
performing the same or
different law enforcement functions, and a population can only be
assigned once, so it is not possible to
formulate a crime rate for every agency.

Knowing the trend of the rate of crime can be an
important measure of the social health of our communities. An
unusually high rate may be caused by an isolated tragic event, the
location of the jurisdiction in an area with a large industrial zone or
that serves as a tourist destination, and a
low
rate may be caused by the assignment of crimes to multiple agencies
serving the same area,
only one of which can be assigned the population, or an
error in the number of crimes reported.

The UCR does not include a record of every crime reported to law
enforcement, and every agency does not
submit data in the form that the FBI requests. The
most accurate number of crimes reported are those
involving death. The least accurate is the number of
rapes that are reported. The the number of case of rape
reported does not include attempted rapes. Aggravated Assault
does not include cases of simple
assault, (which are the largest number of assaults reported to police)
and so constitutes only a portion of the total number of
reported assaults. The number of Aggravated Assaults used
here
was arrived at by subtracting the number of Simple Assaults
from the Total Assaults reported by each agency. For
a
few agencies, this process resulted in the generation of a negative
number (their UCR report wrongly indicates that there were more simple
assaults than the total number of reported assaults).

The magnitude of a threat/risk is measured by its frequency and effect.
By this definition crime may well constitute the single
greatest risk/threat we face today. If you have
questions,
comments, or suggestions, please see our FAQ page
